SPECIFICATION forming part of Letters Patent No. 361,296, dated April 19, 1887.

Application led December-14, 1886. Serial No. 221,569. (No model.)

` ence being had therein to the accompanying drawings, in which- Figure l represents an elevation of part of a Window with my invention attached; Fig. 2, a full-sized section of my improvement on the llne w on Fig. l. Fig. 3 shows a section of a wall With anedge view of the window-shutter and its attachments. Fig. 4C is a perspectIve detail. Fig. 5 is a perspective detail, showing part of the inside ofthe shutters when closed. v

This improvement relates to that class of shutter-operators in which the shutter is unfastened and opened by the same handle; and' the invention consists in the peculiar combinations and the construction and arrangement of parts hereinafter more particularly described, and then pointed out in the claims. Referring now to the details of the drawings, A represents a shutter-operator having an arm, B, which operator may be of any wellknown form, but preferably having a vertical shaft, C, carrying said arm B andturned by bevel-gears, and the shaft D operated by the handle E inside the house.

The arm B has a stud, b, which operates in a groove in a guide, F, which groove is of peculiar form, its topbeing inclined in two different directions at f and f', as shown in Fig. 4, for a purpose that will be hereinafter explained.

Attached to the inside and outside ofthe shutters are fastenings G Gr', both of which are alike, each being provided with a base for attaching the same to the shutter, and projecting hook y to catch on the stationary part of the fastenings. These latter are in two forms, one---thatV attached to the Weather-board?- being shown at H in Figs. l and 3, while the other is shown in perspective at I in Fig. 5, and is preferably in theA form of a triangular bar, with slotted ears at the ends to receive screws for fastening the same adj ustabl y to the sill of the window-fastener.

The operation is as follows: By turning the handle E the gears I' and s and the arm B are operated in the usual manner; but as the arm AB moves outward it carries the stud b under the stud b to act on the'inclinef and lift the shutter off of t-he catch II and swing the shutter closed, when the hook g rises over the bar I, and as it again drops it holds the shutter securely fastened. Thus byasingle movement of the handle E in one direction the shutter is unfastened, opened, and fastened back, and by a reverse movement of the same handle the shutter is again unfastened, closed, and fastened shut. It will be observed that the pivot or shaft ofV the arm B is not in line with the pintle of the hinges, so that as the shutter opens and is thrown back against the 'wall the stud b moves along the groovein the guideF,whereby, although it operates under the incline f in lifting the shutter before the opening of the same, it operates under the inclinef when the shutter is wide open.

'Ihe fastening-hooks have an additional function besides that of mere fastenings, viz: In conjunction with the catch H and bar I, they support the shutter at all times, whether opened or closed, and prevent it from sagging. This is an important improvement, and it is entirely prevented by the use of `,these catches.

Instead .of using a stud, b, I may curve the free end of the arm upward, as shown in dotted lines in Fig. l, and should consider the two forms as the equivalents of each other; but I deem the former preferable.

Having thus described the preferable form of carrying out my invention, but without limiting myself to the exact construction shown, what I claim is 1. The combination, with a shutter and a guide-bar, I, connected therewith, of arotary vertical shaft, a rigid arm firmly attached thereto and moving horizontally, and a liftingstud between said arm and guide-bar, sub.- stantially as described.

2. The combination, with :L shutter and :t swinging arm, B, of :t guide, as F, having :in incline, f, under which the arm acts to lift the shutter previous to opening the same, substantially as described.

3. The combination, with :L shutter and :t swinging arm, B. of a guide, as F, provided with inclines f f under which the arm B acts in lifting the shutter before opening` and closing, respectively, substantially as described.

4. The combination of :L shutter having rigid fastenings restingr on fixed supports when open and closed, with a shutter-operator pro vided with thc arm B, :uid a guide, F, having inclinesff", under which scid arm works, sub- 15 stantialiy as described.

5. The combination,with the fastenings G G on each shutter, of the bar I, constructed to receive and hold both fnstenings, substantial] y as described.

In testimony whereof I affix my signature, in presence of two witnesses, this 11th day of December, 1886.
